摘要

This manuscript reports new experimental measurements of density and viscosity of tetrahydrofurfuryl alcohol + 1-alkanols (1-propanol to 1-heptanol) mixtures, at 0.1 MPa and over a temperature range from 293.15 K to 323.15 K. PC-SAFT was used to correctly predict the increase in density of the mixture with decreasing 1-alkanol. Furthermore, the Redlich–Kister correlation allowed to correctly model experimental data of excess molar volume and viscosity deviation, whose adjustable parameters were obtained by a criterion that guaranteed a deviation lower than 4.5 % for each mixture and at each temperature.
